摘要

本文介绍了虚拟现实(VR)在电影演员的vfx增强场景排练中的应用。视觉特效场景背后的障碍是,演员必须在单色的绿色或蓝色屏幕前拍摄,几乎没有任何线索表明他们周围的数字场景。当场景包括与数字合作伙伴的互动时,问题会变得更糟。演员们必须假装他们与想象中的生物共享布景,而事实上,他们是在一个空荡荡的布景上独自一人。为了支持演员完成这项复杂的任务,我们在表演排练中引入了VR技术,不仅让演员沉浸在数字场景中,还为他们提供了排练戏剧的高级功能。事实上,我们的方法结合了一个完全互动的环境和一个动态的场景特征,让演员在排练对话和动作的同时,以自己的速度熟悉虚拟元素。该系统可实现单用户或多用户的互动性和创造性排练。此外,由于有广泛的支持平台,VR排练可以在片场或场外进行。我们进行了初步研究,以评估VR训练是否可以取代经典训练。结果表明,经过vr训练的演员的表演和普通训练的演员一样好。此外,在我们的实验中,所有的被试都更喜欢VR训练而不是经典训练。

Virtual Reality Rehearsals for Acting with Visual Effects
This paper presents the use of Virtual Reality (VR) for movie actors rehearsal of VFX-enhanced scenes. The impediment behind VFX scenes is that actors must be filmed in front of monochromatic green or blue screens with hardly any cue to the digital scenery that is supposed to surround them. The problem is worsens when the scene includes interaction with digital partners. The actors must pretend they are sharing the set with imaginary creatures when they are, in fact, on their own on an empty set. To support actors in this complicated task, we introduce the use of VR for acting rehearsals not only to immerse actors in the digital scenery but to provide them with advanced features for rehearsing their play. Indeed, our approach combines a fully interactive environment with a dynamic scenario feature to allow actors to become familiar with the virtual elements while rehearsing dialogue and action at their own speed. The interactive and creative rehearsals enabled by the system can be either single-user or multi-user. Moreover, thanks to the wide range of supported platforms, VR rehearsals can take place either on-set or off-set. We conducted a preliminary study to assess whether VR training can replace classical training. The results show that VR-trained actors deliver a performance just as good as ordinarily trained actors. Moreover, all the subjects in our experiment preferred VR training to classic training.
